Description

Technical Field

[0001] This invention relates to the field of wire trough production technology, and more specifically, to a continuous pressing and hot stamping device for wire troughs. Background Technology

[0002] Cable trays, also known as wiring ducts, are typically fixed to walls or ceilings to store and protect electrical wires, network cables, and data cables. They generally consist of a tray body and a cover. The tray body holds the cables, while the cover seals the tray body for protection. Plastic cable trays are usually produced by extruding and cooling the tray body and cover separately, then pressing and assembling them together. After cutting and packaging, they are then sold wholesale. As people's living standards improve, they pay more attention to the appearance of cable trays. Cable trays with patterns or decorative designs are popular. However, existing cable trays with patterns or designs are typically produced by cutting the cable tray first and then printing the patterns or designs separately using equipment. This adds an extra step to the production process, increasing time and costs. Furthermore, current cable trays generally use screen printing or transfer printing for patterns or designs, which are not resistant to friction and are easily scratched. Summary of the Invention

[0003] To overcome the shortcomings of the prior art where patterns or designs are printed separately after cutting the wire groove, which increases production costs, this invention provides a continuous pressing and hot stamping device for wire grooves. After the wire grooves are pressed and assembled, patterns are printed continuously, simplifying the production process, shortening production time, and reducing production costs.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a continuous pressing and hot stamping device for wire grooves, comprising: a base, a pressing assembly and a hot stamping assembly respectively connected to the base; the pressing assembly includes a first bracket connected to the base, a first roller and a second roller respectively rotatably connected to the first bracket, and a first driving unit connected to the first roller; the hot stamping assembly includes a second bracket connected to the base, a third roller and a fourth roller respectively rotatably connected to the second bracket, a patterned part and a first heating element respectively connected to the third roller, and a second driving unit connected to the third roller; the hot stamping assembly is located behind the pressing assembly, the first roller and the second roller are used to press the wire groove, the first heating element is used to heat the patterned part, the patterned part is used to hot stamp patterns on the surface of the wire groove, and the first driving unit and the second driving unit are respectively mounted on the first bracket and the second bracket.

[0005] The hot stamping assembly is located behind the pressing assembly, meaning it follows the processing steps. During processing, the groove first passes through the pressing assembly for pressing and assembly, and then passes through the hot stamping assembly for hot stamping the pattern. In the pressing assembly, the first drive unit drives the first roller to rotate, and the second roller is the driven roller. The groove includes a groove body and a top cover. The top cover abuts against the first roller, and the groove body abuts against the second roller. The groove body and the top cover are pressed and assembled together under the rolling and squeezing action of the first and second rollers. After the groove is assembled, it moves to the hot stamping assembly. In the hot stamping assembly, the second drive unit drives the third roller to rotate, and the fourth roller is the driven roller. The patterned part is connected to the third roller. Specifically, the patterned part is set on the working surface of the third roller. When the third roller is working, the top cover passes by and simultaneously abuts against the third roller and the patterned part. The patterned part directly contacts the top cover of the groove. The surface of the patterned part has raised patterns. The first heating element heats the patterned part, thereby hot stamping the pattern onto the top cover. The pressing and hot stamping components operate simultaneously, both using a rolling drive to move the wire trough. The wire trough passes through the pressing and hot stamping components sequentially, allowing for continuous production in a single cycle. This continuous process reduces production time and lowers costs. Simultaneously, the device uses a heated hot stamping method to create grooves and patterns on the top cover of the wire trough. The resulting patterns are wear-resistant, scratch-resistant, and will not peel off, resulting in high quality. The shapes of the first, second, third, and fourth rollers and the patterned section are designed according to the wire trough product's shape, making it suitable for various specifications of wire trough products. Specifically, during operation, the first heating element is fixed relative to the third roller, rotating together with it. An external power supply is connected to the first heating element via an electric slip ring. Both the first and second drive units can be motors.

[0006] Preferably, the third roller includes a roller body rotatably connected to the second bracket and a cover connected to the roller body; the roller body is connected to a limiting member, and an elastic member is fitted on the limiting member; the patterned portion is slidably connected to the roller body, the limiting member passes through the patterned portion and is connected to the roller body, the limiting member is used to limit the sliding stroke of the patterned portion, the two ends of the elastic member abut against the patterned portion and the limiting member respectively, and the roller body has a groove for accommodating the patterned portion on the side near the cover.

[0007] The patterned part slides within the groove, and a limiting component restricts its movement. An elastic component is fitted onto the limiting component to reset the patterned part. This arrangement controls the contact pressure between the patterned part and the groove, which is related to the spring force. By adjusting the spring force, the contact pressure can be controlled, improving the hot stamping quality and preventing stringing during printing. Additionally, the first heating element heats the patterned part, which is movable. The heating wire of the first heating element can be directly mounted on the back of the patterned part and connected to it via an electrical wire. Alternatively, the heating wire can be mounted on the third roller, allowing heat to be conducted through the roller body or air to heat the patterned part. A cover covers the limiting component and the elastic component. The cover serves as part of the third roller, contacting the groove, and also protects the limiting component and the elastic component. The cover is detachably connected to the roller body.

[0008] Preferably, the limiting member is threadedly connected to the roller body, and the cover is provided with a clearance portion for avoiding the elastic member and the limiting member.

[0009] The limiting component and the roller body are detachably threaded, which facilitates the replacement of the patterned part and the elastic component. At the same time, the cover is provided with a clearance part to avoid the elastic component and the limiting component, so that the elastic component and the limiting component can be directly removed from the clearance part, further facilitating the replacement of the elastic component and making it easier to adjust the abutting pressure of the patterned part, and further adapting to hot stamping of grooves of different materials.

[0010] Preferably, the first roller, the second roller, the third roller, and the fourth roller are all provided with anti-slip parts.

[0011] Anti-slip features are incorporated to prevent the wire groove from wobbling, jumping, or shifting, thus further ensuring the quality of hot stamping. These anti-slip features can be achieved by creating anti-slip grooves or raised textures on the working surfaces of the first, second, third, and fourth rollers. Alternatively, they can be provided with anti-slip strips or layers with high friction, such as high-temperature resistant rubber strips or layers.

[0012] Preferably, it further includes a temperature measuring component connected to the base, the temperature measuring component being signal-connected to the first heating element, and the temperature measuring component being used to monitor the temperature of the patterned portion.

[0013] A temperature sensing component is set up to monitor the temperature of the patterned section. This component is signal-connected to the first heating element, thus correlating the temperature of the first heating element with the temperature of the patterned section, allowing for more precise temperature adjustment. Since the patterned section operates at a higher temperature than the third roller and is rotating, the temperature sensing component measures the temperature of both the third roller and the patterned section, selecting the highest temperature as the measured value for the patterned section. Specifically, a temperature sensor can be selected as the temperature sensing component.

[0014] Preferably, the pressing assembly further includes a second heating element connected to the first roller. The second heating element is used to heat the first roller and preheat the wire groove before hot stamping. The second heating element is signal-connected to the temperature measuring assembly.

[0015] The first roller abuts against the upper cover in the groove. The second heating element is set to heat the first roller. When the first roller abuts against the upper cover, it preheats the upper cover before hot stamping. Preheating the upper cover first can reduce the temperature difference between the upper cover and the patterned part, which is more conducive to hot stamping and can also further avoid the occurrence of stringing during hot stamping.

[0016] Preferably, it further includes a lifting component that is vertically slidably connected to the first bracket, a third drive unit connected to the lifting component, the second roller being rotatably mounted on the lifting component and thus indirectly rotatably connected to the first bracket, the third drive unit driving the lifting component to move up and down, and the connection structure between the fourth roller and the second bracket being the same as that of the second roller.

[0017] The second and fourth rollers are each rotatably mounted on different lifting components. The third drive unit drives the lifting components to move up and down, thereby controlling the distance between the second and fourth rollers and the first and third rollers, and thus controlling the squeezing force on the wire groove. This also allows for the processing of wire grooves of different sizes. The third drive unit can be a telescopic cylinder or a screw rotatably connected to the lifting components. The screw is threadedly connected to both the first and second supports, and then connected to a handwheel or motor. The handwheel or motor drives the screw to rotate forward and backward, thereby driving the lifting components to move up and down.

[0018] Preferably, the base is connected to a plurality of hot stamping components, all of the second brackets are slidably connected to the base, and all of the second brackets are connected to a fixing member, the fixing member being used to fix the second bracket to the base.

[0019] The second brackets of multiple hot stamping components are slidably connected to the base, thereby allowing all hot stamping components to slide to the base. Adjusting the spacing between the components adjusts the spacing of the hot stamping patterns. The fixing components can be bolts threaded to the second brackets, with the bolt ends abutting against the base. Tightening the bolts secures the second brackets. Furthermore, before operation, the positions of the patterned parts in each hot stamping component are calibrated, for example, ensuring all patterned parts face downwards. During operation, all third rollers rotate at the same speed to prevent the patterns stamped by the front and rear hot stamping components from mixing. Additionally, the first bracket is also slidably connected to the base and is also connected to a fixing component.

[0020] Preferably, the base is provided with a plurality of positioning grooves, the fixing member passes through the first bracket and is connected to the positioning grooves, and the distance between adjacent positioning grooves is equal to the circumference of the third roller.

[0021] The positioning groove is connected to the fixing component to increase the fixing effect of the fixing component. At the same time, the distance between adjacent positioning grooves is equal to the circumference of the third roller, which makes it easier to adjust the position and further avoids the situation where the patterns printed by the front and rear hot stamping components are mixed together.

[0022] Preferably, the printed pattern of the patterned part is coarser the farther away from the pressing component, thereby gradually making the pattern printed on the groove coarser.

[0023] The coarser the print on the patterned part, the greater the deformation of the hot-stamped part on the cover, and the greater the required hot-stamping temperature and pressure. It is also more likely to cause hot-stamping stringing. By setting up multiple hot-stamping components, and making the print on the patterned part coarser the farther away from the pressing component among the multiple hot-stamping components, the cover gradually passes through multiple hot-stamping components, making the print on the cover gradually coarser, further avoiding stringing during hot-stamping.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] After the wire grooves are assembled by the pressing assembly, they directly proceed to the hot stamping assembly for pattern printing. The production process is relatively continuous, with the production time for continuous pressing and hot stamping being very similar to that of individual pressing production. This simplifies the production process, significantly reduces production time, and improves efficiency. Simultaneously, the hot stamping assembly, similar to the pressing assembly, uses a rolling drive to move the wire grooves. While the hot stamping assembly is printing the pattern, it also presses the wire grooves together, preventing incomplete pressing. Attached Figure Description

[0037] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0038] Example 1

[0039] like Figure 1-2 As shown, a continuous hot stamping device for wire grooves includes: a base 1, a pressing assembly 2 and a hot stamping assembly 3 respectively connected to the base 1; the pressing assembly 2 includes a first support 201 connected to the base 1, a first roller 202 and a second roller 203 respectively rotatably connected to the first support 201, and a first drive unit 204 connected to the first roller 202; the hot stamping assembly 3 includes a second support 301 connected to the base 1, a third roller 302 and a fourth roller 303 respectively rotatably connected to the second support 301. 3. A patterned part 304 and a first heating element 305 are respectively connected to the third roller 302, and a second driving unit 306 is connected to the third roller 302; the hot stamping assembly 3 is located behind the pressing assembly 2, the first roller 202 and the second roller 203 are used to press the groove, the first heating element 305 is used to heat the patterned part 304, the patterned part 304 is used to hot stamp patterns on the surface of the groove, and the first driving unit 204 and the second driving unit 306 are respectively mounted on the first bracket 201 and the second bracket 301.

[0040] The hot stamping assembly 3 is located behind the pressing assembly 2, that is, after the processing steps. During processing, the groove first passes through the pressing assembly 2 for pressing and assembly, and then passes through the hot stamping assembly 3 for hot stamping of the pattern. In the pressing assembly 2, the first driving unit 204 drives the first roller 202 to rotate, and the second roller 203 is the driven roller. The groove includes a groove body 12 and a top cover 11. The top cover 11 abuts against the first roller 202, and the groove body 12 abuts against the second roller 203. The groove body 12 and the top cover 11 are pressed and assembled together under the rolling and squeezing action of the first roller 202 and the second roller 203. After the groove is assembled, it moves to the hot stamping assembly 3. In the hot stamping assembly 3, the second drive unit 306 drives the third roller 302 to rotate, the fourth roller 303 is the driven roller, and the patterned part 304 is connected to the third roller 302. Specifically, the patterned part 304 is set on the working surface of the third roller 302. When the third roller 302 is working, the upper cover 11 passes by and simultaneously abuts against the third roller 302 and the patterned part 304. The patterned part 304 directly contacts the upper cover 11 of the wire groove. The surface of the patterned part 304 is provided with raised patterns. The first heating element 305 heats the patterned part 304, thereby hot stamping the pattern on the upper cover 11. The pressing assembly 2 and the hot stamping assembly 3 work simultaneously, and both use a rolling drive to move the wire groove. The wire groove passes through the pressing assembly 2 and the hot stamping assembly 3 in sequence. The pressing and hot stamping of the wire groove can be completed in a single continuous production. The process is continuous, the production time is short, and the production cost is reduced. Meanwhile, this device uses a heating and hot stamping method to stamp grooves into patterns on the upper cover 11 of the wire trough, producing patterns that are wear-resistant, scratch-resistant, and will not peel off, resulting in high quality. The shapes of the first roller 202, second roller 203, third roller 302, fourth roller 303, and patterned part 304 are designed according to the shape of the wire trough product, making them suitable for various specifications of wire trough products. Specifically, during operation, the first heating element 305 is fixed relative to the third roller 302, and the first heating element 305 rotates together with the third roller 302. An external power supply is connected to the first heating element 305 through an electric slip ring. Both the first drive unit 204 and the second drive unit 306 can be motors.

[0041] The beneficial effects of this embodiment are as follows: After the wire groove is assembled by the pressing component 2, it directly arrives at the hot stamping component 3 for pattern hot stamping. The production process is relatively continuous, and the production time for continuous pressing and hot stamping is very similar to that for individual pressing production. This simplifies the production process, greatly reduces production time, and improves production efficiency. Simultaneously, the hot stamping component 3, similar to the pressing component 2, uses a rolling drive to move the wire groove. While the hot stamping component 3 is stamping the pattern, it also presses the wire groove, preventing incomplete pressing of the wire groove.

[0042] Example 2

[0043] The difference between Example 1 and Example 2 is as follows:

[0044] like Figure 3 As shown, the third roller 302 includes a roller body 3021 rotatably connected to the second bracket 301 and a cover 3022 connected to the roller body 3021. A limiting member 4 is connected to the roller body 3021, and an elastic member 5 is fitted onto the limiting member 4. A patterned portion 304 is slidably connected to the roller body 3021. The limiting member 4 passes through the patterned portion 304 and connects to the roller body 3021, limiting the sliding stroke of the patterned portion 304. Both ends of the elastic member 5 abut against the patterned portion 304 and the limiting member 4, respectively. A groove for accommodating the patterned portion 304 is provided on the side of the roller body 3021 near the cover 3022. The limiting member 4 is threadedly connected to the roller body 3021, and a clearance portion 3022a is provided on the cover 3022 to avoid the elastic member 5 and the limiting member 4. The first roller 202, the second roller 203, the third roller 302, and the fourth roller 303 are all equipped with anti-slip parts 6. Figure 1 As shown, it also includes a temperature measuring component 7 connected to the base 1. The temperature measuring component 7 is signal-connected to the first heating element 305 and is used to monitor the temperature of the patterned part 304. The pressing component 2 also includes a second heating element 205 connected to the first roller 202. The second heating element 205 is used to heat the first roller 202 to preheat the wire groove before hot stamping. The second heating element 205 is signal-connected to the temperature measuring component 7.

[0045] The patterned part 304 is slidably installed in the groove. The limiting member 4 restricts the movement of the patterned part 304. An elastic member 5 is fitted on the limiting member 4 to reset the patterned part 304. This arrangement can control the contact pressure between the patterned part 304 and the groove. The contact pressure is related to the spring force. By setting the size of the spring force, the contact pressure can be controlled, improving the hot stamping quality and preventing stringing during hot stamping to some extent. In addition, the first heating element 305 heats the patterned part 304. The patterned part 304 is movable. The heating wire of the first heating element 305 can be directly set on the back of the patterned part 304 and connected to the heating wire by an electric wire. Alternatively, the heating wire of the first heating element 305 can be set on the third roller 302, and heat can be conducted through the roller body 3021 or air to heat the patterned part 304. The cover 3022 covers the limiting member 4 and the elastic member 5. The cover 3022 serves both as part of the third roller 302, abutting against the groove, and as a protective element for the limiting member 4 and the elastic member 5. The cover 3022 is detachably connected to the roller body 3021. The limiting member 4 is detachably threadedly connected to the roller body 3021, facilitating the replacement of the patterned part 304 and the elastic member 5. Simultaneously, the cover 3022 has a clearance 3022a to allow the elastic member 5 and the limiting member 4 to be directly removed from the clearance 3022a, further facilitating the replacement of the elastic member 5 and improving the adjustment of the abutting pressure of the patterned part 304, thus adapting to hot stamping of grooves made of different materials. An anti-slip part 6 is provided to prevent the groove from shaking, jumping, or shifting, further ensuring the quality of the hot stamping. The anti-slip part 6 can be formed by providing anti-slip grooves or anti-slip ridges on the working surfaces of the first roller 202, second roller 203, third roller 302, and fourth roller 303. Alternatively, it can be formed by providing anti-slip strips or anti-slip layers with high friction, such as high-temperature resistant rubber strips or layers, on the working surfaces of the first roller 202, second roller 203, third roller 302, and fourth roller 303. A temperature measuring component 7 is provided to monitor the temperature of the patterned part 304. The temperature measuring component 7 is connected to the first heating element 305, thereby correlating the heating temperature of the first heating element 305 with the temperature of the patterned part 304, allowing for more precise adjustment of the temperature of the patterned part 304. Since the temperature of the patterned part 304 is higher than that of the third roller 302 and it is in a rotating state during operation, the temperature measuring component 7 measures the temperature of the third roller 302 and the patterned part 304, and the highest temperature is selected as the measured temperature value of the patterned part 304. Specifically, the temperature measuring component 7 can be a temperature sensor.The first roller 202 abuts against the upper cover 11 in the groove. The second heating element 205 is set to heat the first roller 202. When the first roller 202 abuts against the upper cover 11, it preheats the upper cover 11 before hot stamping. Preheating the upper cover 11 first can reduce the temperature difference between the upper cover 11 and the patterned part 304, which is more conducive to hot stamping and can further avoid the occurrence of stringing during hot stamping.

[0046] Furthermore, such as Figure 3-4 As shown, the first heating element 305 in this embodiment is a heating rod, which is specifically connected to an external power source through an electric slip ring. The second heating element 205 has the same structure as the first heating element 305.

[0047] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0048] Example 3

[0049] Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences:

[0050] like Figure 1 and Figure 4 As shown, it also includes a lifting member 8 that is vertically slidably connected to the first bracket 201, a third drive unit 9 connected to the lifting member 8, a second roller 203 that is rotatably mounted on the lifting member 8 and thus indirectly rotatably connected to the first bracket 201, the third drive unit 9 driving the lifting member 8 to move up and down, and the connection structure between the fourth roller 303 and the second bracket 301 is the same as that of the second roller 203. Figure 4 As shown, the base 1 is connected to multiple hot stamping components 3. All second brackets 301 are slidably connected to the base 1, and all second brackets 301 are connected to a fixing member 10, which is used to fix the second bracket 301 to the base 1. The base 1 is provided with multiple positioning grooves 101. The fixing member 10 passes through the first bracket 201 and connects to the positioning groove 101. The distance between adjacent positioning grooves 101 is equal to the circumference of the third roller 302. The printing pattern of the patterned part 304 is coarser the farther away from the pressing component 2, thus gradually making the pattern printed on the groove coarser.

[0051] The second roller 203 and the fourth roller 303 are rotatably mounted on different lifting components 8. The third drive unit 9 drives the lifting components 8 to move up and down, thereby controlling the distance between the second roller 203 and the fourth roller 303 and the first roller 202 and the third roller 302, thus controlling the squeezing force on the groove and adapting to the processing of grooves of different sizes. The third drive unit 9 can be a telescopic cylinder or a screw rotatably connected to the lifting component 8. The screw is threadedly connected to the first bracket 201 and the second bracket 301, and then the screw is connected to a handwheel or motor. The handwheel or motor drives the screw to rotate forward and backward, thereby driving the lifting component 8 to move up and down. The second bracket 301 of the multiple hot stamping components 3 is slidably connected to the base 1, thereby making all the hot stamping components 3 slidably connected to the base 1. Adjusting the distance between each hot stamping component 3 adjusts the distance of the hot stamping pattern. The fixing component 10 can be bolted to the second bracket 301, with the bolt end abutting against the base 1. Tightening the bolt fixes the second bracket 301. Furthermore, before operation, the positions of the patterned portions 304 in each hot stamping assembly 3 are calibrated, for example, ensuring that all patterned portions 304 face downwards. Then, during operation, all third rollers 302 rotate at the same speed, preventing the patterns stamped by the front and rear hot stamping assemblies 3 from mixing together. Furthermore, the first bracket 201 is also slidably connected to the base 1, and the first bracket 201 is also connected to a fixing member 10. Positioning grooves 101 are connected to the fixing member 10, increasing the fixing effect of the fixing member 10. Simultaneously, the distance between adjacent positioning grooves 101 is equal to the circumference of the third roller 302, making position adjustment easier and further preventing the patterns stamped by the front and rear hot stamping assemblies 3 from mixing together. The coarser the print on the patterned part 304, the greater the deformation of the hot-stamped part 11, the greater the required hot-stamping temperature and pressure, and the easier it is for the hot-stamping to produce stringing. By setting up multiple hot-stamping components 3, and the patterned part 304 with the furthest distance from the pressing component 2 among the multiple hot-stamping components 3, the print on the top cover 11 gradually becomes coarser as it passes through the multiple hot-stamping components 3, further preventing stringing during hot-stamping.

[0052] Furthermore, such as Figure 4 As shown, the temperature measuring component 7 includes multiple temperature sensors, and temperature sensors are respectively provided below the pressing component 2 and each hot stamping component 3.

[0053] Furthermore, such as Figure 2 and Figure 4 As shown, all the first brackets 201 and second brackets 301 are slidably connected to the base 1 via a slide rail assembly. The slide rail assembly includes a slide rail and a slider. All the first brackets 201 and second brackets 301 share the slide rail, and each first bracket 201 and second bracket 301 is connected to a slider, which is slidably connected to the slide rail. Furthermore, a positioning groove 101 is provided on the slide rail, and a fixing member 10 is provided on the slider.

[0054] The remaining working principles and processes of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
